Answer:
A "geographer" who works with "city governments" to help layout new parks and streets might be a cartographer.
Step-by-step explanation:
- A cartographer is the one who is responsible for making precise and accurate maps of different places by studying the features and the orientation of "natural and man-made objects" at that particular place.
- To prepare layouts of new parks and streets already built or to be built in the city, the city government would hence need to consult a cartographer.
